ATTORNEY effected by means of a worm gear 18 (Figs.

.same 1s mounted a dog 36, one, for each and 1A and 6) mounted upon a shaft 19 to which the gear 12-is also attached. A worm 20 en gages the worm gear 19 and is mounted upon rotated by the shaft 21, which shaft extends to the left and into the control box (Figs. 8 and 9). At the end of the shaft 21 is mounted a sprocket 22 operated by a sprocket chain 23 from a lower sprocket 24, mounted on a shaft-25, upon the outer end of which is mounted an operating wheel 26, provided with a handle 27. The several sprockets and gears are proportioned so that one and'one-half turns of the. operating wheel 26 effect a longltudinal movement of the act-n doors, connected thereto by thelocking pin orpins14, from closed to open position, or vice-versa. V p V i LThe' positionof the operating handle 27 indicates when the said door or'doors are open or closed, asshown in Fig. 8. V

A hand wheel 30 (Figs. 89), designated as the small hand wheel, is mounted on a shaft 31, to the opposite endof which is attached a sprocket 32 operating a chain 33 which, in turn, operates an upper sprocket 34 on the end'of the shaft 35 (Figs. 1, 1A, 8 and 9). This shaft 35 extends above all of the doors ofthe group or block and upon. the

individual door, (Figs. 2, 3, 4, 5 and? Each 7 dog 36 is provided with an extension' 36 po sitioned to engage a boss 37 on a locking member 38.

The locking member 38 is loosely mounted on the shaft 35 and is provided with bosses 39 and 40 positioned to engage av lug 41 on the locking dog 42, which latter is mounted upon a shaft 43, one for eachdoor, the lockmg dog 42 being provided with another lug 44 alsopositioned to be engaged by the boss 40 on the locking member 38. A stop lug '45 on the locking member 38 -limits the move ment thereof. i M

, Referring to Figs. 3, 4 and 5, a latch operatingplate is mounted for vertical movement on guide pins 51 and 52' and is provided witha finger 53 positioned to engage a latch 54, pivotally mounted at 55 upon a carrier 56, which is pivotally mounted at 57 and provided; with a second finger 58 positioned to be engaged by aco-operating finger 59 on the locking member 38, the operation of which will be explained.

An individual door control disk 60is provided with a notch 61, the notch being differently positioned on the several individual disks for each door, which disks are mounted upon a shaft 62 (Figs. 1, 1A, 2, 3, 4, 5; 8 and 9) This shaft 62 is provided at its end which projects into the control box (Figs. 8 and 9) withagear63 meshing with a gear 64 at the upper, end of a shaft 65, at the lower end of whlch lsmounted a gear 66 meshing with simultaneously,

a gear 67' operated by and mounted upon a sleeve 68 rotatably and loosely mounted upon the shaft 31. At the outer end of this sleeve tated tobring the letter D to the top. ating bar 9 sufiicient to move the door or This operation of the hand Wheel 30 rotates the shaft 35 and the several dogs 36, rotatlng 42 fromv the locked position shown in Fig. 4 to the unlocked position shown in Fig. 3 and permitting the several locking pins 14 to drop into the slots 16, connecting the several doorswith the actuating bar 9.

,The door operating wheel 26 (Figs. 8 and 9) is now rotated by means 0" the handle 27, in the direction of the arrow, one and onehaif turns to bring the handle 27 from the indication Look to the indication Open (Fig. 8). This rotates shaft 21 with the worm and gear mechanism (Fig. 1A and Fig. 6) and moves the actuating bar 9 longitudinally and slidesthe doors to the open posi- To close the doors,'this operation is reversed, as will be understood. I

' To lock the doors when closed, the hand wheel 30 is rotated to the left to bring the letter L=to the top and then to bring the letter D to the top, which moves the parts from the position shown in Fig. 3 to that shown in Fig. 4, in which position the locking dogs 42 are engaged in the slots 16 and the locking pins 14 are raised out of engagement therewith.

To operate any single door, bring the dial 1;. Wheel 69 (Figs. 8 and 9) to position with the 64 and 63, and control disk 60 (Fig. 4) bringing the notch 61 on the disk 60 for the desired door under the pointed end of the latch 54, which drops into this notch, as indicated in dotted outline in Fig. 4. Now the small hand wheel 30 8) is turned to the right bringing the letter;B thereon under the indicator 70. This rotates shaft 31 (Fig. 9 sprocket 32, chain33, sprocket 34, shaft 35 and dog 36, causing lug 36 to disengage the latch plate 50 and the finger 53, previously engaged-withthe latch 54, as shown in Fig. 5, allowing the latch to drop into the notch 61 in the disk 60, as shown in Fig. 4 in dotted the. several members 38, as heretofore described, and movlng the several locking dogs inent,*a,shaft extending adjacent" all of said locking dogs, a-v:,separ ate operating dog for each adapted to operatively connect one of :said: doors'with said actuating bar, asepa- J .rate locking dog foreach-of said doors pivotalIy mOImted-and adapted to be swung into position to selectively disengage said locking pin therefrom-andto lock said door against movement, a shaft extending adja- V cent all of said locking'dogs, a plurality' of Operating dogs,' one for'each door, attached to said shaft; a plurality of locking members ,looselymou'nted on said shaft and each positioned adjacent and adapted to beengaged and operated byjone of saidoperating dogs and adapted to engageand operate one of said 'locking dogs,;a hand wheel provided with position indicationsthereon operative- 1y". connected to and adapted to rotate said shaft to eiiectfthe operation of the aforesaid associatedmembers, and means for effecting I 2.
